Agreed completely.
I think I knew you had Russian bees, just has not registered for a while.
I like the OAV for bees that DO need treated because of the lack of residue and other harmful side effects. For a new beekeeper it removes the RISKS associated with treating incorrectly and or at the wrong time. Just one less thing to worry about. If it makes the new beekeeper FEEL better, he, or she can treat with the OAV, and of they did not NEED the treatment it still does not harm the bees, and DOES kill a few mites along the way. I am not advocating treating if the bees do not need it, just using a product that allows a margin of error without harmful side effects. Being overwhelmed and not fully understanding the different treatments and methods, and/or what the threshold is or how to check it accurately comes with time and experience.
I failed alcohol washes, sugar shakes etc the first few times I did them.. I was not even entirely sure what I was looking for back then. Scooping bees in to a jar was quite stressful for me, and I can only assume it was the bees as well.. It took me a bit of time to gain confidence in what I was doing. So being able to treat, even if they didnt need it because they are not SURE, but want to MAKE sure is a great amount of weight removed from the shoulders of a new beekeeper. The stuff I started with scared the bejeesus out of me putting it in the hives. Using something less nasty would have been a lot more reassuring. Again, that is not saying they SHOULD treat without checking, it is saying it gives them the time and confidence to be able to perfect their methods and ability while keeping their bees alive, without harming them from "overcare".
That is what I was trying to get across..
For me, with 40+ hives now, it means I can check 6 to 8 hives, and if the mite levels are high I can treat ALL of the hives. If there are a couple that did not need it, there was no harm done. If I had to check the mite levels on all hives it would be a long day in the bee yard and a lot more bees would die. A little freedom from worry, for a new beekeeper, or an old one!
